Inconel 690 Tubes Manufacturer, Supplier & Stockist in USA

Premium Inconel 690 Tubes for High Temperature & Corrosive Applications

We manufacture, stock, and supply premium-quality Inconel 690 Tubes for demanding industrial applications where exceptional corrosion resistance and elevated temperature performance are essential. Manufactured according to international standards, our tubing delivers outstanding mechanical strength, dimensional accuracy, and long service life under aggressive operating conditions.

Alloy 690 Tubing is a nickel-chromium alloy containing approximately 30% chromium, providing superior resistance to oxidizing chemicals, sulfur compounds, nitric acid, and chloride-induced stress corrosion cracking. Because of these properties, Nickel Alloy 690 Tube is extensively used in heat exchangers, condensers, steam generators, nuclear reactors, petrochemical plants, and pollution control equipment.

As an experienced Inconel 690 Tubing Stockist, we maintain ready inventory in seamless, welded, ERW, and electric fusion welded tubing to meet urgent project requirements worldwide.

What are Inconel 690 Tubes?

Inconel 690 Tubes are manufactured from UNS N06690, a high-chromium nickel alloy developed for applications requiring excellent resistance to oxidation and corrosion at elevated temperatures. The alloy performs exceptionally well in environments containing chlorides, sulfur compounds, and oxidizing acids.

Also known as Werkstoff Nr 2.4642 Tubes, this alloy offers higher chromium content than Inconel 600, making it significantly more resistant to stress corrosion cracking and high-temperature oxidation.

Our product range includes:

• ASTM B163 Inconel 690 Tubes
• ASTM B167 Alloy 690 Tube
• ASME SB163 UNS N06690 Tubing
• UNS N06690 Heat Exchanger Tubes
• JIS NCF 690 Seamless Tubing
• Inconel 690 ERW Tubes
• Inconel 690 Electric Fusion Welded Tubes

Each tube undergoes stringent quality inspections to ensure compliance with international specifications.
